JAMES COLLINS, OF CBAWFOBDSVILLE, INDIANA.

Specification forming part of Letters Patent No. 117,745, dated August8, 1871.

To all whom it may concern:

Be it known that I, J AMns COLLINS, of C 1awfordsville, in the county ofMontgomery au d State oi' Indiana, have invented a new and usefulImprovement in Yheel-Iit; and I do hereby declare that the following isa i'ull,clear, and exact description thereof, which will en'able othersskilled in the art to make and use the same, reference being had to theaccompanying drawing forming part of this specification, in which-Figure 1 is a top view oi' my improved machine. Fig.2 is averticalcross-section ofthe same taken through the line .r Jr, Fig. 1. Fig. 3 isa detail view illustrating a modification oi' the clamping device.

Similar letters ot reference indicate correspon ding parts.

My invention has for its object to furnish an improved wheel-pit orapparatus for holding the hubs and spokes oi" a wheel while the spokesare being driven, which shall be simple in construction, convenient inuse, and effective in operation, being so constructed as not only tohold the hub and spokes securely while the spokes are being driven, butalso to gz'iuge the dish of the wheel; and it consists in theconstruction and combination of various parts of the machine, ashereinafter more fully described.

A are the side bars, and B are the cross-bars of the frame of themachine. The cross-bars B are made fast at one end to one of the sidebars A. The other ends oi' the cross-bars B pass through mortises in theother side bar A, and are adjustablysecured in place by wedge-keys C andpins D, several holes being formed in the crossbars B to receive thepins D, so that the machine may be conveniently adjusted according tothe length of the hubs to be operated upon. rllhe middle part of theupper sides of the side bars A are recessed to iform seats for the endsof the hub while being operated upon. E is the guidestati' or bar,against which the point or outer end oi' the hub rests. The staii' orbar E passes down between the standards F, the lower ends of which aresecured to the side bar A ofthe frame.. The bar or staii' E is securedto the standards F by a pin, G, which passes horizontally through thesaid standards and statt' about upon a line with the center of the pointofthe hub. By this construction, as soon as the other or butt end ofthehub is pressed against by the clamping device the staffer bar E willadjust itself to the end or point of the hub. H is the guide-pin, theinner end of which is notched or concaved to receive the upper or outerend of the spoke to be held and driven. The other or outer end of theguidepiu H has a screw-thread formed upon it, passes through the upperpart of the staff or bar E, and has two nuts, I, screwed upon it, oneupon each side oi' the said bar or staff E, so that, by adjusting theposition oi' the said nuts I, the guide-pin H may be adjusted accordingto the length of the hub and the dish of the wheel, the said pin thusserving as a gauge to regulate the dish of the wheel. per part of thestati' or bar E to receive the pin H, so that the said pin may beadjusted higher or lower as the length of the spokes may require. Theend of the spoke is held in place against the notched or recessed endofthe pin H by thel lever J, the forward end of which is bent or hooked,as shown in Fig. 1, to pass around the said spoke and hold it securelyin place. The hooked lever J is pivoted to the pin H, and is heldforward in its place by the spring K attached to the pin H and pressingagainst the side or" the said lever J, as shown in Fig. l. To the otherside bar A of the trame, directly opposite the but-t end of the hub, issecured a standard, L, the inner face of which is recessed to receive asmall wheel or disk, M, against which the end of the hub rests. Thewheel or disk M is swiveled to the end of a rod, N, that passes througha hole in the sta-ndard L, and against the outer end of which the sideof the lever O rests. The end oi' the lever O is pivoted to a supportattached to the side bar of the frame by being inserted in a hole insaid support, or in any other convenient manner. The lever O, near itsother end, has a pawl or plate, P, formed upon or attached to it to takehold of the teeth of the rack Q attached to the side bar A of the frame,so that, by adjusting the lever 0, any desired amount of pressure may beappli-ed to the end of the hub to clamp it securely in place. Ii'desired, the rod N may have a screwthread, a', cut upon it to work in ascrew-thread or nut in the standard L, in which ease a crank,

R, is attached to or formed upon the outer end of the lsaid rod N, sothat the pressure may be regulated by turning the said crank R. The re-Several holes are formed in the upvolving disk M enables the hub to bepressed with sufficient force against the staii or bar E Without undulyincreasing the friction.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. The guide-staff or bar E, constructed and operatingin connection with the standards F, pin G, and end ofthe hub,substantially as herein shown and described, and for the purpose setforth.

2. The adjustable supporting` and gauge-pin H, nuts l, lever J, andspring K, constructed and operating` in connection with the adjustableguide staff or bar E and outer ends ofthe spokes, substantially asherein shown and described, and for the purposes set forth.

JAMES COLLINS. Witnesses:
